IMPROVEMENT IN CAR-TRUCKS.

Specification forming part of Letters Patent No. 151,465, dated June 2, 1874 ,1 application filed December 12, 1873.

To all whom it may concern:

Be it known that I,- JASPER BIDLAGK, of Marilla, in the county of Erie and State of New York, have made certain Improvements in Railroad-Gar Trucks, of which the following is a specification:

This invention consists of a peculiar manner of bracing the main beams and frame of a railroad-ear truck, which, while possessing great strength, shall reduce the weight ofthe truck, the construction and arrangement of which is fully hereinafter described.

In the drawings, Figure lis a side elevation; Fig. A2, a top plan.

A Al are the usual wooden frames or side pieces of' the truck, to which the usual axleboxes a c are attached, and in which the journals of the wheels b b run. These wheels are provided with divided or double axles B B, meeting in the center, the journaled ends c c ruiming in a central journal-box, l, as shown in Fig. 2. This box C is firmly attached to a central horizontal timber, D, which is a very important adjunct in strengthening the whole truck, as well as holding these center boxes C. Another timber, E, sets at right angles to the other, directly across it andbetweenthe wheels, as clearly shown. The ends of this rest on the side pieces A A', and also on the central timber D. It is held in place by bent iron side braces d d', each end bolted to the side pieces A A', and also bolted in the center to the cross pieces E. An additional center brace, d", is provided, bolted in the center to the cross-piece at f, and the ends bolted or otherwise fastened to the central timber I)-` Another brace, c, similar to this last, will be set underneath the truck, as shown in Fin'. 1, to give additional strength and aid in sustaining the load, the weight of which comes in the center of these trucks, and relieves the strain on the outer journal-boxes to a great extent, facilitating the runnin g of rolling stock, especially around curves, and taking oft' the great bearing on the outside wheels, which now have to sustain the bulk of the load. In order to strengthen and retain firmly in their proper position the longitudinal and transverse beams or braces D and E, I secure to the said beams the four brace-rods F F, the ends of which are secured, respectively, to the longitudinal beam D and cross-beam E, and in their position they resemble a rectangle. By means of these braces great strength is imparted to the beams D and E and the entire frame-work of the truck increased in strength. The longitudinal brace D is important to snstainthe boxes C for the journals of the double axles, and my method of bracing is suoli as to give the greatest lightness as well as strength to the trucks. These trucks may be lengthcned out and two or more sets of wheels employed. An end piece, G, will be fastened, also, to the ends of the trucks, if required, as shown in the drawings, to aid in strengthening them.

I claim- In combination with the frame of a car truck and the longitudinal and transverse beams D and E, the braces F, secured in place in the manner and for the object set forth.

In witness whereof I have hereunto signed my name in the presence of two subscribing witnesses.

JASPER BIDLACK.
